ADOLF J. MARSCIIALL, OF LITTLEFALLS, NEW, YORK.

ELECTRIC GAS-LIGHTER.

SPECIFICATION forming part of Letters Patent No. 699,202, dated May 6,1902. Application filed March 8,1901. Serial No. 50,324. (No modeLl Toall whom it may concern:

Be it known that I, ADOLF J. ll/IARSCHALL, a subject of the King ofDenmark, and aresident of Littlefalls, in the county of Herkimer andState of New York, have invented a new and useful Improvement inElectric Gas-Lighters, of which the following is a specification.

This invention relates to that class of portable electric gas-lighterswhich comprise a dry battery or element arranged in the handle of theimplement, a tubular stem which extends upwardly from the handle andcontains in its perforated end a platinum coil which has one of itsterminals connected with the base of this stem and the other with aninsulated wire which extends through the stem to the other pole of thebattery, and a device for closing the circuit through the platinum coilat will.

The object of my invention is to produce a gas-lighter of this generalcharacter which is simple in construction and convenient in operationand which permits of the ready and convenient renewal of the battery.

In the accompanying drawings, Figure 1 is a sectional elevation of myimproved gaslighter. Fig. 2 is an elevation of the lower portion of thesame at right angles to Fig. 1.

Fig. 3 is a horizontal section in line 3 3, Fig. 1.

Like letters of reference refer to like parts in the several figures.

A represents the casing of the handle, constructed of tin or othersuitable metal and having the form of a long cylindrical can or cupwhich is closed at the bottom and has at its open upper end ascrew-thread a.

B represents the zinc pole of the battery or element which is arrangedwithin the casing and insulated therefrom. This pole is somewhat smallerin diameter than the surrounding casing, and the intervening space isfilled with wax, pitch, or other suitable nonconducting material b.

is a. circuit-closing spring or arm which 18 secured at its lower end tothe casing A, on the inner side thereof,and which projects with its head0 or upper end outwardly through an opening 0' inthe casing. This headhas the form of a thumb-piece or push-button and enables the spring orarm to be pressed inwardly against the zinc pole for closing thecircuit.

D is the carbon pole, which has the form of a'rod arranged centrally inthe zinc pole in the'usual way.

E is the packing, arranged between the two poles and consisting,usually, of powdered carbon and manganese peroxid dampened with asolution of sal ammonia.

e is the usual lining of filter-paper, arranged against the inner sideof the zinc pole. The battery is sealed with pitch or wax, as usual.-

The carbon pole D is provided above the packing with a semi ellipticalcontactspring F.

G represents a screw-cap which is applied to the upper threaded end ofthe casing A and which carries the tubular stem II and the insulatedwire I. The latter projects with its lower end through aninsulating-plugt'in the lower end of the tubular stem and makes contactwith the spring F when the cap G is screwed upon the handle. It isobvious that the arrangement may be reversed and the contact-spring besecured to the wire and make contact with the carbon pole.

represents the platinum coil, arranged in the upper end of the tubularstem and having one of its terminals connected with the insulated wire Iand the other with the screw cap G in any suitable manner -for instance,as shown, by a connection'lt", running to the tubular stem, or, ifpreferred, by a wire running to the cap G. The stem is provided oppositethe coil with openings Z, through which the gas finds access to thecoil;

m is a hook formed on the tubular stem, near the upper end thereof, forhanging up the implement.

In the use of the implement the push-button c of the springG can beconveniently operated by the hand holding the handle of the implement.When the battery is exhausted, it is unscrewed with its casing from thecap G and replaced by a new casing and battery, which can be furnishedat comparatively small cost.

I claim as my invention 1. In an electric gas-lighter, the combina tionof aconducting-battery casing, a battery having an internal and anexternal pole 10- cated in and insulated from said casing, alighting-coil, a conducting-support for the same With which one terminalof said coil is electrically connected, means for detachably andelectrically connecting the coil-support with the casing, a conductorconnecting with the other terminal of the coil and detachable with saidcoil-support from said casing, a contact for connecting said conductorwith said internal pole of the battery, and a hand-controlled means formaking electrical connection between said casing and said external poleof the battery, substantially as set forth.

2. In an electric gas-lighter, the combination with a lighting-coil, asupporting screw cap and tubular stem, an insulated Wire arranged Withinsaid stem, and a lighting-coil having one terminal connected with saidcap ADOLF J. MARSOIIALL.
